The underwriting agreement
provides that the obligations of the underwriters to purchase the notes included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the notes if they purchase
any of the notes.

Notes sold by the underwriters
to the public will initially be offered at the initial public offering prices set forth on the cover of this prospectus supplement. Any 2023 notes sold by the underwriters to securities dealers may be sold at a selling concession from the initial
public offering price not in excess of 0.350% of the principal amount of the 2023 notes. Any 2028 notes sold by the underwriters to securities dealers may be sold at a selling concession from the initial public offering price not in excess of 0.400%
of the principal amount of the 2028 notes. Any such securities dealers may resell any 2023 notes purchased from the underwriters to certain other brokers or dealers at a discount from the initial public offering price not in excess of 0.175% of the
principal amount of the 2023 notes. Any such securities dealers may resell any 2028 notes purchased from the underwriters to certain other brokers or dealers at a discount from the initial public offering price not in excess of 0.200% of the
principal amount of the 2028 notes. If all the notes are not sold at the initial offering price, the underwriters may change the offering price and the other selling terms.

We expect that the delivery of the notes will be made against
payment on December 8, 2017, which is the third business day following the date of this prospectus supplement (this settlement cycle being referred to as T+3). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market
generally are required to settle
